Hi guys
I've searched around without finding the answer to my questions.

I've got a 2015 ram and I live in Arizona where they requested yearly emissions testing after the vehicle is 5 years old.

I'm looking to tune the truck.

My initial thought was to tune it with double r diesels emissions compliant tuning, however the truck has 41k miles and I really don't want to deal with replacing the DPF filter after this one clogs.
That and I want a bit more sound.

So if I do a full delete, it seems like I can disconnect the EGR and leave all emissions components under the hood installed without issue.
I will just have to install a race pipe in place of the DPF filter

Now when my time comes to emissions the truck, can I reinstall the DPF to the exhaust, return to stock and plug everything back in?

If so, any issue with check engine lights?

Then after I pass reverse the process once again.
